Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a flexible laryngoscope that avoids contamination of the body. Background Technology

[0002] During laryngeal examinations, the larynx is located deep within the body and has a complex physiological structure, making it impossible to directly visualize. Therefore, a laryngoscopy is necessary. Flexible video laryngoscopes combine the flexibility of electronic bronchoscopes with the wide field of view of rigid video laryngoscopes, greatly improving the ease of endotracheal tube manipulation. However, during insertion of the flexible video laryngoscope into the pharynx, it encounters contaminants such as secretions and blood from the oropharynx. These contaminants adhere to the imaging tip, contaminating the lens and obscuring the view, thus increasing the difficulty of the examination. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a flexible laryngoscope that avoids contamination of the body, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible laryngoscope for avoiding bodily contamination, comprising a laryngoscope body, a display screen at the top of the laryngoscope body, a mounting block on one side of the laryngoscope body, an insertion part connected to the bottom of the laryngoscope body, an insertion head at the end of the insertion part, and a contamination-proof imaging mechanism on the insertion head.

[0005] Preferably, the mounting block is provided with a connecting pipe head.

[0006] Preferably, the imaging mechanism includes a camera device installed inside the insertion head, a groove is provided on the insertion head, an inner ring is provided inside the insertion head and sleeved on the groove, the inner ring is provided with a nozzle and a suction tube, and the inner ring is connected to a liquid injection tube.

[0007] Preferably, the nozzles are provided in a plurality of numbers and are evenly distributed in a ring on the inner sidewall of the inner ring.

[0008] Preferably, the nozzle is angled and the opening faces the surface of the camera device.

[0009] Preferably, the suction tubes are provided in three parts, one end of which passes through the inner ring and the opening is located on the inner wall of the groove, and the other ends of the three suction tubes are connected to a main suction tube.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention proposes a flexible laryngoscope that avoids contamination of the body. During laryngeal examination, the insertion part and insertion head are inserted into the patient's larynx, and the camera device can take pictures of the larynx. If secretions, blood, or other contaminants in the oropharyngeal cavity adhere to the surface of the camera device, they will obstruct the view. Because a suction tube is provided, the suction tube can remove contaminants from the front end of the camera device. In addition, the injection tube injects cleaning fluid into the inner ring and sprays it out from the nozzle. The cleaning fluid washes the mirror surface of the camera device, and works in conjunction with the suction tube to keep the surface of the camera device clean, thus ensuring a clear view.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 3 This utility model provides a technical solution: a flexible laryngoscope that avoids contamination of the body, including a laryngoscope body 1, a display screen 2 at the top of the laryngoscope body 1, a mounting block 3 on one side of the laryngoscope body 1, and a connecting tube head on the mounting block 3.

[0018] The bottom of the mirror body 1 is connected to an insertion part 4, and an insertion head 5 is provided at the end of the insertion part 4. The insertion head 5 is provided with a pollution-proof shooting mechanism, which includes a camera device 11 installed inside the insertion head 5. The camera device 11 includes a camera and a light. The end of the camera device 11 needs to be kept clean to ensure a good shooting view. A groove 6 is provided on the insertion head 5. An inner ring 7 is provided inside the insertion head 5 and fits onto the groove 6. A nozzle 8 and a suction tube 10 are provided on the inner ring 7. Several nozzles 8 are provided and are evenly distributed in a ring on the inner side wall of the inner ring 7. The nozzles 8 are inclined and their openings face the surface of the camera device 11. Three suction tubes 10 are provided. One end of the suction tube 10 passes through the inner ring 7 and its opening is located in the inner wall of the groove 6. The other ends of the three suction tubes 10 are connected to a main suction tube. The main suction tube is connected to a connecting pipe head on the mounting block 3. This connecting pipe head is connected to a negative pressure machine. When the negative pressure machine is started, it can suck away the contaminants in the groove 6.

[0019] The inner ring 7 is connected to an injection pipe 9, which is connected to a connecting pipe head on the mounting block 3. This connecting pipe head can be connected to a cleaning fluid storage device, and cleaning fluid can be injected into this connecting pipe head. The cleaning fluid enters the inner ring 7 along the injection pipe 9, and then can be sprayed towards the camera device 11 along the direction of the nozzle 8.

[0020] In actual use, when performing a throat examination, the insertion part 4 and the insertion head 5 are inserted into the patient's throat, and the camera device 11 can take pictures of the throat. If secretions, blood, or other contaminants in the oropharyngeal cavity adhere to the surface of the camera device 11, they will obstruct the camera's view. Because a suction tube 10 is provided, the suction tube 10 can suck up the contaminants at the front end of the camera device 11. In addition, the injection tube 9 injects cleaning fluid into the inner ring 7 and sprays it out from the nozzle 8. The cleaning fluid rushes towards the mirror surface of the camera device 11, which can clean the surface. At the same time, it works with the suction tube 10 to keep the surface of the camera device 11 clean and ensure a clear camera view.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
